I am working on a robotics project in which I need to power two 25 kg*cm servo motors, which will stall, I have a DC 6V 10A power supply for the motors, I am using an ESP 32 to control the servos with PWM. My question is how can I power the servo motors externally in terms of implementation, will this require soldering/stripping the wires off the servos? If so what components (protoboard, terminal blocks, etc..) do I need? Because according to google breadboards cant handle more then 1A. Thanks!
Please post a link to the servo product page.
Do you know how much stall current these servos can generate and at what voltage they need.
If in deed you can use a 10A power supply then strip board will vaporise unless you put some 18 SWG tinned copper wire across the tracks that will be taking that current.
Solderless bread board is right out.
4.8-8.4V and stall current is around 2-4 Amps
The product page has none of the usual specifications, but at a guess, the stall current is around 3 Amperes. So, plan on a power supply capable of at least 3 A per servo, or at least 6 A for two.
Servos briefly draw the stall current every time they start moving.
In terms of the actual implementation, do you guys have any recommendations
or tips on how to tackle this?
Tackle what?
I thought that is what I gave in post #4?
I am new to soldering, can you guide me to any references or tutorials that carry out something similar to what i'm trying to implement
Adafruit and Sparkfun both have good soldering tutorials.
First Learn to solder.
Second here is an example of a board I made from strip board to carry a 3A servo load consisting of 4 servos.
First the top of the board. Notice on the left hand side there are copper wire links between the spacing of the servo's two power leads. These bridge gaps where otherwise the current would travel through the strip board track. Also notice the thick wire to carry the current. I had to enlarge the holes in the strip board to do this.
Next the back of the board showing where these links come out, and bend over the servo pins, this is a bit hard to see.
Also note that the soldering is not as neat as it could be, because I did it in the month following my stroke, two years ago, which left my right hand severely impaired. But hopefully you get the idea.
